encodeNstOrderShape {DNAshapeR} | R Documentation

## Encode n-st order shape features DNAshapeR can be used to generate feature vectors for a user-defined model. The model can be a shape model. There are four structural parameters including MGW, Roll, ProT and HelT. The second order shape features are product terms of values for the same category of shape features at adjacent positions.

### Description

Encode n-st order shape features DNAshapeR can be used to generate feature vectors for a user-defined model. The model can be a shape model. There are four structural parameters including MGW, Roll, ProT and HelT. The second order shape features are product terms of values for the same category of shape features at adjacent positions.

### Usage

    encodeNstOrderShape(n, shapeMatrix, shapeType)

### Arguments

`n` | A number indicating n-st order shape encoding
`shapeMatrix` | A matrix containing DNAshape prediction result
`shapeType` | A character name of shape (MGW, Roll, ProT, HelT) features

### Value

featureVector A matrix containing encoded features. shape feature is represented as continuous numbers
